I'm a recent convert and absolutely loving nodal. I have it hooked up to a couple of synths and groove boxes with much enjoyment.
One of those is the Kaossilator pro which works surprisingly well with nodal since you can draw the cc graphs on the arrows which makes it really easy and quick to come up with melodies. Those patterns can also apply to something like a vocoder which suddenly makes the Kpro actually quite an interesting prospect as the patterns become repeatable rather than random hit-or-miss fingerpainting :)
Good work coding person/team, thank you :)
